Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members.Defects of alloy pipe and solutions:North Santa Cruz,Keep the combustion supporting gas and use it reasonably to avoid fracture of the welding interface. Problems in the welding of steel wire mesh skeleton composite pipe are common, which should be prevented or solved.Whether I-section steel is ordinary or light, due to the relatively high and narrow section size, there is a large difference in the moment of inertia between the two main sleeves of the section. Therefore, it can only be directly used for members bent in the plane of their web or form lattice stress members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application.Langfang City,Because alloy pipe is a very unique pipe fitting we must use appropriate methods to carry out installation in the case of installation, so as to ensure the performance index of the data. Generally, when installing alloy pipes,North Santa CruzHow much is 120 I-beam per meter, we will use some flanges and elbows to fix them, so as to ensure that the raw materials can be fixed very well. Therefore, when we carry out use, we must ensure the quality of flanges and elbows, so as to ensure the actual effect of alloy pipe assembly. If there are instrument panel components that must be assembled on the pipeline, they must be installed together.Alloy pipe is a spiral seam seamless steel pipe, which is made of hot-rolled strip steel coil, often processed by warm extrusion and welded by automatic double wire double side arc welding process. The alloy pipe sends the hot-rolled strip steel to the welded pipe unit, and the hot-rolled strip steel is extruded through multiple passes. The hot-rolled strip steel is rolled slowly to produce annular pipe material with open mouth gap. Adjust the reduction amount of the extrusion roll to control the welding gap at ~ mm and make both sides of the weld flush.Introduction to product knowledge of alloy pipe:

→ compared with the concrete structure,North Santa CruzHow much is cold drawn welded pipe, the I-steel structure can increase the service area by %, reduce the self weight of the structure by % - %, and reduce the structural design internal force.According to the section shape, the steel pipe is divided into:Last week, the billet in North China market showed a slight rebound trend. The billet quotation in Tangshan, the leading city, rose first and then stabilized in four trading days, with a strong wait-and-see atmosphere in the market. Affected by the almost stagnation of festival procurement, although the phase snail is still running at a low level, due to the small billet resources in the market, the steel mills unexpectedly rose, due to the continuous increase of capital pressure and the downturn in the transaction of downstream finished materials, and then after quenching and low-temperature temperingCarburizing: carburizing is the process of penetrating carbon atoms into the surface layer of steel. It also makes the low-carbon steel workpiece have the surface layer of high-carbon steel, house construction and building decoration. Its fracture will always be found in the production manufacturing and key marketing of alloy pipe, That is, many stages of production and processing are not done well. Another is that the seasoning is not enough and the proportion of chemical molecules is wrong. There are all reasons.Whether I-section steel is ordinary or light, because the section size is relatively high and narrow, the moment of inertia of the two main axes of the section is quite different, so it can only be directly used for members bent in the plane of their web or form lattice stressed members. It is not suitable for axial compression members or members with bending perpendicular to the web plane, which makes it very limited in the scope of application. I-beam is widely used in buildings or other metal structures.

Dry processing technology: after passivation treatment, parts shall be dried with air compression or hot gas, or drying treatment or air drying can be selected.Product survey,Generally, there are many passivation methods for alloy tubes, the common ones are high temperature passivation or sodium cyanide passivation.The advantage of the reinforcement mesh system is ecological. It is filled with natural stone materials. There is a gap between the stone materials to allow plants to grow in it. It can also plant plants on it. It has the dual effects of engineering slope protection and plant slope protection. The Ecological Grid mat is a combination with a height of cm ~ cm,North Santa CruzWelded pipe price, mostly a multi grid box separated by spacer mesh.Stages needing attention in the production and manufacture of alloy tubesNorth Santa Cruz,Performance parameters and application scope of I-beamDue to the relatively high and narrow section size of ordinary I-beam and light I-beam, the moment of inertia of the two main axes of the section is quite different, which makes it very limited in the scope of application. The use of I-beam shall be selected according to the requirements of design drawings.The production process can be summarized as follows: pre leveling → finishing → straightening → post leveling. Flat steel / A / B steel with width of -, thickness of -, rectangular section and slightly pure edge. Flat steel can be finished steel, or it can be used as blank for welded pipe and thin slab for laminated thin plate.
